Sharp Blade

Using a 5-axis precision machine, the blade edge is precisely grinded to improve uniformity, and the cutting groove is formed in a single piece.

Surface hardening treatment has a high hardness HRC65 and long life.

Fast cutting

Keep the surface of the workpiece upright during operation to avoid damage to the tool due to uneven force.

The first cut needs to be slightly shaken to allow for quick cutting. When cutting hard materials, you can add water or coolant to get better drilling results.

Fine material organization

Made with high speed steel round bars that are heat treated and tempered to ensure uniform tissue, high strength, and sharper edges.
